Question

Quizplus · Accepted Answer

The midsagittal plane divides the body into equal left and right halves, making it the most appropriate choice for Dr. Mitchell's incision during open heart surgery. The transverse plane would divide the body into upper and lower halves, which is not ideal for accessing the heart. The frontal plane would divide the body into anterior (front) and posterior (back) halves, which also does not provide optimal access to the heart. The sagittal plane is a general term that can refer to any plane that divides the body into left and right portions, but does not specify that it will be dividing the body equally.
